发明名称 TRACING MECHANISM OF TORQUE ADJUSTABLE WRENCHES
摘要 A torque adjustable wrench includes an adjusting rod extending from an end of the shank of the wrench and a first toothed surface are longitudinally defined in an outer periphery thereof. A longitudinal positioning groove is defined in the adjusting rod to form a blank area of the first toothed surface. An end cap is connected to the grip which is rotatably connected to the shank and includes second toothed surface which is engaged with the first toothed surface. A positioning member is connected to the end cap and includes a positioning tongue which can be removably engaged with the longitudinal positioning groove. When the torque is set, the grip is pulled to remove the positioning tongue from the longitudinal positioning groove and the user may operate the wrench. The use can trace the original setting by inserting the positioning tongue into the longitudinal positioning groove.
